Array Fit to Curve not working
First, select the path and apply its Rotation &amp; Scale with CtrlA, otherwise it will make your object rotate. Go in Edit mode and in the N panel, bring back its vertices radius to 1 to correct the applied scale (and Tilt to 0 unless you want one).
Put the object at the same position as the path's origin: Select the path, ShiftS &gt; Cursor To Selected, then select the object, press ShiftS &gt; Selection to Cursor.
In the Curve modifier, find the good Deformation Axis, which seems to be X.
